You can get a CJ manual, but their are so few wires you need from CJ, that I didn't get one. As far as your air filter, I went simple. I honestly just took a K&N cone filter that was the correct inside diameter and slipped it directly over my throttle body. It works, and keeps the clutter down very well.
